Found for sale on auction website without a species name, it's grafted onto a Myrt and it's referred to only as 'button'. Definitely appears to be a Loph. It's not the greatest price, but in this country it's a rare opportunity methinks.
I'm more concerned if there's a way to tell if it's a diffusa though, because I ain't paying for one of those. :/
